How this comparison works
Comparing eSIM offers is hard because every provider slices data and validity differently. To keep it honest, RoamV fixes one basket - 20GB / 30 Days - and looks up what each provider charges for it in Greece. Nothing else changes between the rows above.
- Same package for everyone. 20GB of data, valid 30 days, for use in Greece.
- Public list prices. Taken from each provider's own Greece page, in US dollars, before any promo code.
- Ranked by price only. The cheapest plan is listed first. Nobody can pay to move up.
- Direct links. Every price links to the exact Greece plan it refers to, so you can check it yourself in one click.
Before you buy an eSIM for Greece
- Check your phone. You need an eSIM-capable, carrier-unlocked phone - most iPhones from XS onwards, Pixel 3 and later, and recent Samsung Galaxy S and Z models.
- Data-only is normal. Travel eSIMs for Greece usually give you mobile data, not a local phone number. Your usual number stays active for WhatsApp, Telegram and iMessage.
- Install before you fly. Buy and install over Wi-Fi at home; most plans only start counting once the eSIM connects to a network in Greece.
- Check hotspot and top-ups. Not every plan allows tethering, and top-up prices are not always as competitive as the first purchase.
- 20GB in 30 days is enough for maps, messaging, social media and a moderate amount of video for most travellers. Heavy streaming needs more.

How does RoamV compare eSIM prices?
We fix one package - 20GB / 30 Days - and record what each provider charges for it in Greece. Prices are public list prices in US dollars, taken from each provider's own page on August 14, 2026, and the table is sorted from cheapest to most expensive. No provider can pay for a better position.
Will an eSIM work with my phone in Greece?
Yes, if your phone supports eSIM and is not carrier-locked. That covers iPhone XS and newer, Google Pixel 3 and newer, and recent Samsung Galaxy S, Note, Fold and Flip models. On most phones you can check under Settings by looking for "Add eSIM" or "Add mobile plan".
Can I keep my own phone number while using a travel eSIM?
Yes. A travel eSIM for Greece is a second line on your phone. Your home SIM stays in place, so you keep your number and your messaging apps, while data runs over the cheaper travel plan. Turn roaming off on the home line to avoid surprise charges.
When should I buy and install the eSIM?
Buy it before you leave and install it over Wi-Fi - the QR code or activation link arrives by email within minutes. The plan's 30 days normally start when the eSIM first connects to a network in Greece, not when you buy it, but check the provider's own wording.
Are these prices final?
They are the list prices we recorded on August 14, 2026. Providers change prices, run promotions and adjust local taxes, so treat this page as a shortlist and confirm the final amount on the provider's checkout page for Greece.
